Since the are many different kinds of computers, running different OS's, connected by different physical links there needs to be some standard way for these computers to talk to each other. IP or Internet Protocol is what is called a "network layer" communication protocol. It's at this layer that your computer or device has its IP address. At a level above the "network layer" we have the "transport layer". TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are two examples of "network layer" protocols. TCP and UDP are built on top of IP, adding features like checksums or resends.
